ABSTRACT

BACKGROUND

1. Field of the Invention

The field of invention relates generally to the fitting of golf equipment and the manufacturing of golf equipment and more particularly to systems and methods designed to improve a golfer's swing and manufacture golf equipment customized to individual golfer's swing.

2. Related Art

A wide variety of methods have been used to form clubs have been used. Specifically, golf club heads have been forged or cast and then ground or machined, and then polished to achieve desired dimensions and appearances. However, these processes have a number of short comings.

Further, golf club heads have generally been manufactured with average dimensions based on an average user without any regard to the specific needs and swing dynamics of specific golfers. This was due to the expense and/or time required made customizing a head mold to incorporate design changes extremely impractical. Thus, to reduce cost and/or save time, a common mold has been used for the head design regardless of the swing dynamics of users. However, not all golfers are identical and many golfers may benefit from optimization of club design parameters such as lie angle, loft angle, or other design parameters. Through post-manufacturing processing, such as grinding or bending with a vice, may allow some custom fitting of clubs, these processes may have limited effectiveness and can create additional problems such as metal fatigue or weakening of the club.

Additionally, existing manufacturing techniques may also require additional post processing, such as grinding, due to manufacturing tolerances. Further, existing techniques have limitations in the shapes and dimensions that can be produced.

Therefore, there is a need for golf club heads that can be more customized based on a specific user's swing dynamics, as well as manufacturing methods that can produce a wider variety of shapes with tighter manufacturing tolerances.

SUMMARY

A general purpose of present application is a method of manufacturing a golf club head that can customize more club design parameters to a specific user's swing dynamics. Various embodiments of the present application may provide a golf club head for playing golf made by a method including providing a powdered metal; and applying a controlled source of energy to the powdered metal layer by layer to form a golf club head, wherein the golf club head is formed as a metallic head having a unibody construction without any welds.

Additionally, some embodiments may provide a method of manufacturing a golf club head with less material waste by generating a computer model of a golf club head, providing a quantity a powdered material, applying a controlled source of energy to a used portion of the quantity metal layer by layer to form the golf club head, and recapturing an unused portion of powdered material and saving the unused portion of the quantity of metal powder to be used for other manufacturing.

Other features and advantages of the present application may become more readily apparent to those of ordinary skill in the art after reviewing the following detailed description and accompanying drawings.

DETAILED DESCRIPTION

Certain embodiments disclosed herein provide for a method of manufacturing a golf club head. However, although various embodiments of the present invention will be described herein, it is understood that these embodiments are presented by way of example only, and not limitation. As such, this detailed description of various alternative embodiments should not be construed to limit the scope or breadth of the present invention as set forth in the appended claims.

FIG. 1 provides a flow chart showing a manufacturing process 100 for a custom golf club according to an embodiment of the present application. In action 105, the user is interviewed to provide initial background information to be used to design the custom golf club. Specifically, a user may be asked to fill out a questionnaire regarding the User's playing statistics. The User's statistics may include, but are not limited to height, weight, years of playing golf, handicap, putts per round, and #rounds per year. Additionally, the user may also be asked about the current golf tendencies including: trajectory of shots, swing path (i.e. hook, slice, etc.) and consistency of shots. Further, the user's goals regarding distance, ball trajectory, drawing, fading the ball, etc.

After the user interview in action 105, the user's current clubs may be measured in action 110 to obtain current club design parameters that may be effecting the User's golf shots. In particular, a variety of current club design parameters may be measured including loft, lie, face angle, hosel offset, club length, club weight, club swing weight, shaft weight, shaft flex, grip size, grip weight, and any other parameters as would be apparent to a person of ordinary skill in the art.

After the design parameters of the user's current clubs are measured in action 105, the user's swing dynamics are analyzed in action 115. Specifically, a user's swing dynamics or Launch parameters with several clubs may be measured with a launch monitor (such as trackman, foresight, etc.). Using the launch monitor, a variety of swing dynamics or launch parameters are measured including: head speed, launch angle, backspin, attack angle, ball speed, swing plane angles, club path, spin axis, horizontal launch angle, tempo, and any other parameters as would be apparent to a person of ordinary skill in the art.

After swing dynamics or launch parameters are measured in action 115, design parameters for the custom clubs are determined in action 120 through a fitting process. Specifically, initial fitting clubs determined based on the user's height, swing path, and launch conditions. Then final head and club specifications are determined by fitting for:

-   -   Consistency by adjusting or optimizing club length and lie by         dynamic fitting;     -   Distance by adjusting club loft to optimize spin and clubhead         speed by dynamic fitting;     -   Control by adjusting face angle to optimize side spin by dynamic         fitting; and     -   Playability by adjusting shaft, grip, total weight and swing         weight for best feel.

From this fitting, club design parameters for the head and final club components are determined. Head design specifications are then determined from the fitting process to specify the optimal head design and properties. Thus, the club specifications are determined at least in part from the results of the dynamic fitting process.

After the design parameters are determined in action 120, a computer model of the club head is generated in action 125. Thus, rather than modifying (i.e. by bending, adjusting weight) of existing parts, a club head computer model is designed based on the determined design parameters. In some embodiments, the club head id generated by first by selecting a base model (Driver, Fairway Wood, Hybrid, Iron, Wedge, Putter, etc.) from a library of club head models. Then, club design parameters such as volume, loft, lie, face angle, weight, CG properties, inertial properties, shape, offset are entered into the base model which is then updated based on the user's required specifications. Additionally, in some embodiments, the face thickness and face thickness geometry (i.e. back face geometry discussed in greater detail below) may be adjusted based on the user's head speed and control tendencies. The customized model can be encoded as a CAD file that will be used to manufacture parts.

After the computer model is generated in action 125, the club head can be manufactured using additive layer manufacturing techniques that use powdered metal and high energy beams (such as a laser or electron beam) in action 130.

Electron Beam Apparatus

FIG. 2A is a diagram illustrating an additive layer manufacturing apparatus using an electron beam, which may be used in a method according to an embodiment of the present application. The manufacturing apparatus 200 includes an electron beam column 205 that generates an electron beam 240 by applying a voltage to a filament 210. The generated electron beam 240 passes through a plurality of lenses 215, 220, and 225 before entering the vacuum chamber 235 where the club head is manufactured. The vacuum chamber 235 includes at least one powder hopper 245 filled with powdered material 255 that will be melted to form the club head.

The powdered materials used can be a wide variety of materials and including most metals including titanium (Ti), Steel, Aluminum (Al), Titanium aluminum alloys (Titanium Aluminide or TiAl), which generally cannot be cast or welded. More specifically, example materials include, but are not limited to:

-   -   Aluminum Alloys ˜2.86 g/cc—such as AlSi10Mg, AlSi12;     -   Steel Alloys ˜7.8 g/cc—such as Stainless Steel, Hot Worked Steel         (stainless and non stainless);     -   Titanium ˜4.5 g/cc—Pure Ti, TiAl6V4, TiAl6V4 ELI;     -   Silver ˜10.3 g/cc;     -   Gold ˜19.3 g/cc;     -   Tungsten ˜19.2 g/cc;     -   Platinum ˜21.4 g/cc;     -   Nickel Based Alloys such as Inconel;     -   Cobalt-Chrome Alloys such as CoCr;     -   Bronze; and     -   TiAl ˜3.8˜4.0 g/cc (titanium Aluminide).

The manufacturing apparatus 200 may also include a heat shield 230 between the electron beam 240 and the powder hopper(s) 245 to prevent melting of the powdered materials 255 prior to being moved into the build tank 260. A rake 250 is provided to move powdered material 255 into the build tank 250 as needed during the manufacturing.

The electron beam 240 is moved across the surface of the powdered material 255 in the build tank 260 based on the computer model to form the club head on a layer by layer basis. As each layer is formed, the club head rests on the start plate 265 and build platform 260. As the club head is formed, the start plate 265 and a build platform 260 are moved downward to provide space form successive layers and additional powdered material 255.

Though an electron beam 240 is used by the apparatus 200 shown in FIG. 2A, the present application is not limited to electron beam based technologies and may include any additive layer manufacturing method that uses powdered material and high-energy beams (such as an electron beam or a laser).

Laser Beam Apparatus

Additionally, FIG. 2B is a diagram illustrating an additive layer manufacturing apparatus 300 using a laser beam, which may be used in a method according to an embodiment of the present application. The additive layer manufacturing apparatus 300 using a laser beam works in a similar manner to the apparatus 200 discussed above. Specifically, the manufacturing apparatus 300 includes an laser 305 that generates a laser beam 350. The generated laser beam 350 is directed at a scanner system 310 that redirects and controls the laser beam 350 to scan the laser beam 350 across the surface of a fabrication bed 315 filled with powdered material 325. Further, adjacent to the fabrication powder bed 315, a powder delivery system 320 is provided to add additional powder material 325 to the fabrication bed 315 as needed. The powder deliver system 320 includes a powder tank 355 filled with powdered material 325, a powder deliver piston 330 that moves upward to push powdered material 325 upward and a roller 335 that directs powdered material to the fabrication powder bed 315.

The scanner system 310 controls the laser beam 350 to move the laser across the surface of the fabrication bed 315 based on the computer model to form the object being fabricated 340, layer by layer. As successive layers of the object 340 are formed, a fabrication piston 345 is retracted downward to gradually lower the object 340 and allow powdered material 325 to flow over the top of the object 340 so that successive layers can be formed.

As with the electron beam apparatus 200 discussed above, a wide variety of powdered materials can be used in the laser beam additive layer manufacturing apparatus 300, including most metals including titanium (Ti), Steel, Aluminum (Al), Titanium aluminum alloys (Titanium Aluminide or TiAl), which generally cannot be cast or welded. Thus, the example materials include the same materials discussed above with respect to the electron beam apparatus 200

Example Structures

These additive layer manufacturing techniques allow manufacturing of surface features having a minimum thickness of Surfaces equal to 300 microns (um). Further, structures of mesh or lattice structures such as those shown in FIGS. 3, 4, 8 and 9 discussed below may have a minimum thickness equal to 150 microns (um).

In some embodiments, the golf head may be manufactured to have a one piece (or unibody) construction, with the face and body (crown, skirt, sole) being formed as a one-piece golf head having hollow or partially hollow sections without a need to weld components together. In some embodiments, a small exit hole may be used to remove powder trapped within hollow areas of the head, but the exit hole can be drilled after the head is manufactured.

Using the additive layer manufacturing techniques, any type of golf club head could be theoretically manufactured based on a generated computer model without a need to retool, producing a variety of clubs faster than methods previously used, such as casting, stamping or forging. Additionally, in some embodiments, using additive layer manufacturing techniques may allow a reduction in waste material because 95˜98% of powder can be reclaimed and used to make more parts. Conversely, forging and casting processes typically produce significant amounts of waste materials.

Additionally, additive layer manufacturing techniques may not require welding of multiple pieces together because clubs can have unibody construction to form a one-piece golf head having a hollow and/or non-hollow sections with no welds. Further, as would be apparent to a person of ordinary skill in the art, if welding is not required, the occurrence of heat affected zones that degrade material properties may be reduced.

The additive layer manufacturing process eliminates thickness and weight variations often caused by grinding to remove material, thermal expansions and shrinkage caused by the lost wax casting process, and inconsistencies and tool wear with conventional tooling processes.

As the additive layer manufacturing processes do not require grinding, which may cause varying thickness or weak spots, tooling, or welding, which may cause thermal expansion or shrinkage, tighter tolerances can be held. These tighter tolerances may also be a reduced need to “re-work” or “repair” out of spec. parts, which can produce a cost savings.

Further, additive layer manufacturing processes may not suffer Flow constraints that casting may experience. Further, additive layer manufacturing processes have higher porosity compared to casting (99.5% dense) and may produce more durable part with thinner structures

Further, additive layer manufacturing techniques may allow the manufacturing of complex geometries not achievable with casting, machining, or forging techniques typically used. FIGS. 3-9 illustrate a sampling of the structures that can be manufactured using additive layer manufacturing techniques.

For example, internal 3D geometries that can not otherwise be manufactured, such as those shown in embodiments (a)-(i) of FIG. 3, may be manufactured. Further, undercuts such as those shown in embodiment (j) of FIG. 3 may be formed without the need for special tooling. Further, separate pockets and slots, typically too difficult to cast or machine, such as those shown in embodiments (k) and (l), can be manufactured using additive layer manufacturing techniques. Thus, iron bodies/soles can be made with undercuts/complex geometries can be manufactured.

Further, 3D lattice/core geometries having a thin skin of metal on either side (1 side), both sides (sandwich), or without a skin on either side (open core), such as those shown in FIG. 4 may also be manufactured. Also, a thin non-metallic skin can also be bonded or joined to the core. These 3D lattice/core geometries are discussed in more detail with respect to FIGS. 8 and 9 below.

Additionally, face inserts have complex variations in face thickness and face geometry, such as those shown in FIGS. 6 and 7 may be manufactured. Specifically, as shown in FIGS. 6 and 7, face inserts having multiple regions of different discrete thicknesses can be manufactured with the thickest regions being located at different portions of the club face depending on design needs. Further, face plates may have complex interior geometries having lightweight cores or lattice structures between skins as shown in FIG. 7 may be manufactured. Since no welding/grinding is necessary, a minimum thickness necessary to have a maximum Coefficient of Restitution can be manufactured, and the inserts still having sufficient durability.

Further, these face inserts can be manufactured to be have complex internal geometries using additive layer manufacturing techniques and then welded to bodies formed using conventional methods such as casting, stamping, or forging. These face inserts can be custom made for based on the player's striking tendencies (i.e. to have max thickness where the player consistently impacts striking face and with thicknesses reducing to maximize the Coefficient of Restitution.

Further, the additive layer manufacturing techniques is not limited to manufacturing the club head and may also be used to manufacture thin metal foils. These thin metal foils may be manufactured and wrapped around on a composite or metal shaft substrate to change or customize the performance characteristics and/or add cosmetic effects to a golf shaft. FIG. 5 a shows an example embodiment of a thin-metal foil 505 and FIG. 5 a shows the thin-metal foil 505 wrapped around a shaft 510. Alternative, a Lightweight lattice structure can be inserted into the hollow inner diameter of the shaft to change the stiffness/performance of the shaft.

As discussed above, complex 3D geometries or 3D lattices can be manufactured as a weight efficient support structure or as a lightweight supporting core for thin walls. FIG. 8 illustrates an enlarged view of an embodiment having thin walls 805, 810 with a plurality of supporting lattices 815 formed between the thin walls 805, 810. Further, FIG. 9 illustrates a plurality of types of 3D lattice structures that can be manufactured using additive layer manufacturing techniques. These include pyramidal lattices (a), tetrahedral lattices (b), 3D-Kagome lattices (c), diamond textile lattices (d), diamond collinear lattices (e), and A square collinear lattices (f). These structural shapes may to increase strength/stiffness, lower weight, and change or optimize the “feel” of the club. The lattice geometries shown in the present application are merely examples and embodiments of the present application are not limited to these shapes. Further, the lattice geometries may also include a 3D mesh designed and optimized to provide the head characteristics desired based on the user's needs.

These “lattice” geometries manufactured using additive layer manufacturing techniques can be applied to any part of a golf club head, including the sole, crown, skirt, etc. and is not particularly limited to only the hitting face. These lattices can also provide an internal support structure to join two sections (for example can be a bridge between the crown and the sole to provide stiffness). Further, the lattice geometries can be manufactured separately or integrated into 1 piece heads.

Additive layer manufacturing can also allow the development of any other details or shapes that have previously been too fine to be cast or machined, such as springs and teeth of a snap clip allowing components (weights) to be attached to an exterior of a club head. The embodiments shown and discussed above are not intended to be limited and are merely provided as examples.

Additionally, as additive layer manufactured golf club components require minimal post manufacturing finishing, that may reduce manufacturing cost or time. Further, additive layer manufacturing discussed above can also allow the “printing” of a surface finish or engineered texture on the face or any exterior surface to influence spin, aerodynamics, or acoustics (sound).

After the heads and other club components are manufactured and finished in action 130 of the FIG. 1, the heads are assembled to the required shafts and grips to achieve the club specifications (length, weight, flex, etc.) determined as optimal during the fitting process in action 135. Thus, a final golf club is supplied that is made specifically for the individual golfer based on his unique player characteristics, and his unique requirements to give optimal performance. The properties and parameters of the head components are determined and manufactured to be customized to the individual to a much greater extent that was previous available.
